ADA Compliance Testing


Criterion’s approach to ADA web compliance, Section 508 and WCAG testing is unparalleled in the industry because we test from a “real world” perspective by including expert accessibility auditors with disabilities. Criterion believes if you want to know whether a website is accessible, ask people with disabilities.

Criterion also emphasizes knowledge transfer throughout every web accessibility audit project by providing our clients with our award-winning ELearning courses, and expert technical support.  This knowledge transfer is a critical component of every Criterion web accessibility audit project because it empowers our clients to manage their Section 508 and WCAG compliance requirements long-term.

Web Accessibility Testing

The use of assistive technologies (software or hardware used by people with disabilities) during our audit process ensures accurate web accessibility test results.

Assistive technologies utilized during Criterion’s ADA web compliance, Section 508 and WCAG testing include:

  • Screen reader
  • Magnifier
  • Text to speech
  • Color contrast analyzers
  • Alternative keyboard devices, etc.

Criterion‘s Accessibility Audit Dashboard

Criterion provides our clients with a highly-customized project dashboard to track the results of our Section 508 and WCAG compliance audits.  This portal provides our clients with a “quick view” project dashboard, and detailed ticketing system that tracks the status and resolution of Section 508 and WCAG accessibility audit issues.

The Accessibility Testing Process

Over the past 16 years, Criterion has created a streamlined testing process to ensure our client’s web accessibility audits are completed within 10 business days.  Below are typical ADA web compliance, Section 508 and WCAG compliance project milestones:

Phase 1

  1. Project Setup – Gather login credentials and validate user acceptance test cases.
  2. Issue ELearning licenses – ELearning course licenses are issued to client’s project team.

  3. 1st Pass Audit – Auditors manually test all unique web pages within your website or application, not just a small sample.  Auditors thoroughly document each unique ADA web compliance, Section 508 and WCAG guideline issue.
  4. 1st Pass HTML Validation Scan – Auditors conduct an automated HTML validation scan to identify approximately 20% of basic Section 508 and WCAG guideline issues.

    Note: Testing the remaining 80% of Section 508 and WCAG guidelines require manual testing by web accessibility audit experts using assistive technologies. Visit Criterion’s Blog for more information about the Limitations of HTML Validation Scans.

  5. Presentation of Audit Results – Upon completion of Phase 1 web accessibility testing, Criterion presents our Section 508 and WCAG test results.
  6. Assign Technical Support – A web accessibility audit support specialist is assigned to your project team to provide Section 508 and WCAG technical support during the remediation process.

Phase 2

  1. Final Audit - After all web accessibility issues identified in our 1st Pass Audit are repaired, Criterion will perform a final Section 508 and WCAG compliance audit.
  2. Final HTML Validation Scan – A final automated HTML validation scan is conducted to ensure all previously identified Section 508 and WCAG accessibility issues have been properly repaired.
  3. WCAG Compliance Documentation – Upon completion of Phase 2 accessibility testing, Criterion will create the following web accessibility certification documents for your records:
    • Criterion WCAG Certification Seal
    • Website Accessibility Statement
    • WCAG Compliance Report
    • Voluntary Product Accessibility Template (VPAT)
    • Government Product Accessibility Template (GPAT)
